BUCKET.

Application filed Ju1y15, 1911.

To all whom it may concern Be it known that I, Jonson HAYWARD, a citizen of the United States, residing at Teaneck, in the county of Bergen and State of New Jersey, have invented certain new and useful Improvements in Buckets, of which the following is a full, clear, and exact specification, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to excavating apparatus and has for its object to provide certain improvements in buckets employed for conveying, dredging and excavating.

Heretofore it has been customary to employ in connection with an orange peel or clam shell bucket two operating lines, one for hoisting and holding the bucket and the other for closing the bucket, the bucket being opened by slacking off on the closing line, when the weight of the material and of the interior mechanism of the bucket is sufficient to cause the bucket to open by gravity and drop the load.

In buckets so constructed, operated by two lines, two drums are of course necessary, one for reeling and unreeling the hoisting line and the other for reeling and unreeling the closing line.

One of the objects of my invention is to provide a bucket for conveying, dredging and excavating, employing only a single line, said line acting to close the bucket as well as to hoist and hold the same in position to drop the load.

A further object of my invention is to provide a self-contained means on a bucket, acting in conjunction with the closing and hoisting line to open the bucket.

A further object of my invention is to dispense with one of the drums, as well as one of the lines heretofore used in the operation of such buckets.

Further objects, such as economy of installation, economy in cost of materials and labor, and simplicity of operation of buckets constructed and operated according to my invention, will be readily apparent from the following description in connection with the accompanying drawings, in which,-

Fig. 4 is a side elevation partly broken away, showing a modification of the invention;

Fig. 5 is an end view of the same;

Fig. 6 is a side elevation showing another modification of the invention;

Fig. 7 is an end view thereof; and

Fig. 8 is an enlarged detail of a portion of the apparatus shown in Fig. 1.

Referring to the construction illustrated, A represents a platform upon which is mounted a pivoted swinging derrick which may follow any of the well known forms of construction and operation and requires no detailed description, it being sufficient to state that B indicates the mast and C the boom,which will be suitably supp0rted,one of the guy cables being shown at E. Upon the platform A is mounted an engine, indicated in whole at F, for driving the hoisting drum G, to which is secured the closing and hoisting line H, which latter passes over a sheave H, mounted upon the mast B, and thence over a sheave I-I suspended from the boom C. The closing and hoisting line H, in my preferred form is divided at its outer end, to form two branches I, I. The bucket proper is also of old and well known construction and needs no detailed description except the statement that it consists of the bowl sections J, J, .the side arms K, K which are pivotally connected by the power shaft L, upon which is mounted the power wheel M having a hub portion M. It also comprises the connecting links N, N which are pivotally connected to the bowl sections J, J and also pivotally secured to the supporting head or block 0, by means of the pintle G, from which pintle are suspended a pair of operating chains P, P, the latter attheir opposite ends being connected to and adapted to be wound about the power wheel hub Iv and, through the rotation of the power wheel, to close and open the bucket. It will be seen that when the power wheel is rotated in one direction the operat-' ing chains P, P wind about the hub M to lift the same and close the bucket, and when the power wheel is permitted to rotate in the opposite direction, said chains will unwind and the power wheel and shaft be lowered by gravity to open the bucket.

Mounted upon the head block O of the bucket, I provide a bearing block Q, comprising the base Q, and the side members Q Upon one side of the said bearing block, and supported by the side members Q is an idler pulley R, over which passes the branch line I, one end of which is connected to the power wheel M. Upon the opposite side-0f the bearing block Q is mounted a motor S, whose armature shaft S has its bearings in the side members Q Upon the shafts is also mounted a winding drum S to which is secured the branch :line I. "'llhe'operating wiresT, T pass from, the motor over the idler pulleyT suspended from theboom C, and thence to a take-up device T rotatably mounted upon the mast B. 'Saidtake-up device, as more clearly showndn Fig. .8, comprises a shaft T having its bearings in side supports T, T,= rigidly connected to the mast -13. Upon saidshaft is loosely mounted the winding drum T to which is connected one end of the conducto1's T,-T, said conductorshaving electrical connection "with annular conductor rings T, T", which are si'litably insulatcd and mounted .upon the annular-flange T and rotated therewith.

Mount-ed upon and preferably formed intogral with the winding drum T 'is a counterweight pulleygmember 'T f to which-is secured one end of a rope T ,'to the other end of which issecured a counterweight T the function of which counterweight is to take up any slack in. the wires T,'T, when the bucket is hoisted.

Rigidlyanounted upon the support T are a plurality-of conducting 'bru'shesT :T,

which also are suitably insulatedand are adapted. to contact with the rotary electrical conductors "-T 'T. 'To the conducting brushes-T T are connected wires T ,-T

whiclrpass down the mast B- and are at their lower ends connected to'a controller Uyof any well. known form, mounted upon the platform A within convenient reach of the engineer-or operator.

'The operatioir'ot the apparatus above described and as shown in Fi s. 1 2 3 and 8 is as follows:

Assuming that the bucket is in closed position, with the power wheel elevated and operating chains wound, as shown in'Figs. 2 and 3, the bucket carrying its loadin positiontodrop the same,a-nd the current oft that shown in Figs. 4- and 5, except that as themotor-lS-is rotated the sprocket wheel tl1e m'otor, the operator turns on the current through'the controller U, the motor is started, which through the shaft 5" operates *the drums winding thereon the-branch line I, dividing the weight carried by thebranch line I and supporting the head of the bucket upon said branch line I, lifting the same relative to the power wheel andload and as itis litted, the operating chains P, F unwind, the power wheel M is rotated and by the change of relative positions of the'head and power wheel the bowl sections open.

In the rotation of the power wheel the branch I is wound thereon. The operation is continued until the power wheel and bucket sections assume the position shown in dotted ilines in Fig; 2.

The bucket, having opened, it is ready for anew load and is dropped in open position ing the' 'b-u'clret lthe sla ck in theconducting:

Referring-to the construction illustrated in Figs. 6 and 7, I providea sprocket'wheel 15 :1nounted -on the bearing' block 16,which sprocket wheel is :fast to the armature shaft 17 of the motor 18. The'hoisting and closline '19 is connected-toasprocket chain 20 :passing through the fair-leader 21: and meshingwith the teeth of the sprocket wheel 15, the lower-end of said chain being connected to'the powerwheeLQQ.

' the lower: end. of the sprocket chain is-paid vention, as defined by the appended claims. Furthermore, my improvement may be applied to other forms of bucket than the one herein illustrated to show the application and operation of my invention.
